“food has no moral value” just statistical anomaly.
Sugar, which has -1000 negative moral value when eaten by a vegan to avoid eating honey, but is totally fine when eaten by anyone else despite all the human exploitation involved, and human flesh which has varying negative moral values for most victims but +100,000 positive value for The Rich, are outliers adn should not be counted
Spiders of course have the combined moral value of the lives of all the insects they’ve eaten (source: Dracula, Bram Stoker, 1897)
